Bits 6 to 4—Periodic Interrupt Flags (PES2-PES0): Specify the periodic interrupt.
Bit 3—RTCEN: Controls the operation of the crystal oscillator for the RTC.
Bit 2—30 Second Adjustment (ADJ): When 1 is written to the ADJ bit, times of 29 seconds or
less will be rounded to 00 seconds and 30 seconds or more to 1 minute. The divider circuit will be
simultaneously reset. This bit is always read as 0. The maximum duration between when the ADJ
bit is set to 1 and when the new setting is reflected in the readout value from the seconds counter
(RSECCNT) is approximately 91.6 µs (when a 32.768 kHz quartz oscillator is connected to the
EXTAL2 pin).
Bit 1—Reset (RESET): When 1 is written, initializes the divider circuit (RTC prescaler and
R64CNT). This bit is always read as 0.
